The cleaning agent of the invention is perfectly suitable for removing dirt and/or residues and is in particular a cleaning agent for hard surfaces such as glass, ceramics, metal or plastic. Also disclosed are uses of the cleaning agent and a production method therefor.

Description

Detergent comprising Saponin and Lactic Acid Bacteria The invention relates to a detergent of natural constituents, in particular for cleaning hard surfaces. Furthermore, it relates to a use and a manufacturing ^¬ method for such a cleaning agent.

Detergents (synonym: cleaners) are understood to mean, in particular, products which serve for the cleaning of articles made of woven and fibrous material as well as hard surfaces in the household, industry or trade. Typically Rei ^¬ cleansers on is dissolved as a concentrate in liquid or solid form is provided ^¬ and then diluted in water by the end user prior to use or.

Conventional detergents contain surfactants and optionally acids. The latter especially when inorganic residues, in ^¬ particular lime, should be removed from surfaces, as is the case for example with sanitary cleaners.

In the past, cleaning agents, which - unusually - live microorganisms include proven. These microorganisms are beneficials such as lactic acid bacteria, which both promote the degradation of soils and, by competitive displacement and production of antibacterial or fungicidal agents, inhibit the growth of harmful microorganisms. In particular, the growth of fecal bacteria of the Enterobacteriaceae family is ge ^¬ inhibits (with representatives such as Escherichia, Salmonella, and Shigella), which both cause bad odors as partially are also pathogenic.

Thus, DE 44 28 624 AI discloses detergents that contain milk ^¬ acid bacteria. Detergents Milchsäurebakte ^¬ rien prove to be odor-resistant, depleting against pathogenic bacteria and fungi.

WO 2004/106481 A2 relates to a composition comprising Ten ^¬ side and selected lactic acid bacterial species.

WO 2010/130541 A1 describes a cleaner for hard surfaces, which contains microorganisms for the degradation of inorganic stains. Lactic acid bacteria are proposed as part of the cleaner.

However, the known in the prior art rice contain niger, which include useful microorganisms, artificial surfactants, which are often in use or production aggressive towards humans and the environment or insufficiently biodegradable.

An object of the present invention is now to provide a detergent with lactic acid bacteria, which contains a more compatible alternative to artificial surfactants, as well as an environmentally friendly manufacturing process for the detergent.

Therefore, the present invention relates to a cleaning ^agent comprising viable lactic acid bacteria, at least one saponin and water. The mass concentration of all saponins in the detergent is at least 0.01%, preferably at least 0.025%, more preferably at least 0.05%, even more preferably at least 0.1%; primarily the mass concentration is at least 0.25%, preferably at least 0.5%, more preferably min ^¬ least 1%, more preferably at least 1.5%, especially at least 2%. The detergent contains at Milchsäurebakte ^¬ rien least 1000 colony bildene units (CFU) per Millili ^¬ ter. The pH of the cleaning agent is below 5. Preference ^¬ example, the cleaning agent of the invention is liquid.

The cleaning agent of the invention is hervorra ^¬ quietly for the removal of soils and / or residues and is in particular a detergent for hard surfaces such as glass, ceramic, metal, stone, wood, or plastic. It can also be used to clean absorbent or non-absorbent, soft surfaces, such as plant components such as leaves. Treated plants are preferably living plants.

The cleaning agent or Herstellungsver inventive drive ^¬ is particularly environmentally friendly because it can no substances TRIPCOM ^¬ men produced from industrially funded fossil fuels, as for example, artificial surfactants laundri ^¬ ren. In particular, the reliance on in many countries indigenous plants in the Production, as mentioned below, enables a balanced ecological balance without unnecessary transport routes.

In addition, the cleaning agent according to the invention acts probio- table. The effect of a probiotic effect is to be understood here as meaning that the lactic acid bacteria contained inhibit the growth and / or survivability of undesired, in particular pathogenic and / or biofilm-forming microorganisms present on the surfaces or articles to be treated, preferably by competitive displacement of the unwanted microorganisms by the lactic acid bacteria contained in the cleaner and / or due to the acid production by the lactic acid bacteria contained in the cleaner. In particular fecal bacteria of the Enterobacteriaceae family (beispielswei ^¬ se with representatives of the genera Escherichia, Salmonella and Shigella) and pathogenic fungi (for example, Ver ^¬ representatives in the genera Candida and Aspergillus) are among the ^¬ sen undesirable microorganisms.

Because of this probiotic effect, it is also appropriate to bring the cleaner preventively on surfaces or Ge ^¬ genständen to prevent colonization by undesirable microorganisms. Furthermore, the cleaning agent is soil friendly and beneficial to plants - therefore it can be used without hesitation, for example, in the garden area.

The present in accordance with the present invention saponins - in addition to their action as surfactants - the positive effects, in particular the mentioned probiotic effect, yet. In particular, this is done by a surprising combination ^¬ act of saponins and lactic acid bacteria.

While there are documents in the prior art discloses the cleaning ^¬ medium with saponins or raw materials for, but have not recognized that in addition a certain con ^¬ concentration of viable lactic acid bacteria is conducive:

EP 2770043 Al relates to a detergent insbeson ^¬ particular detergents, cleaning agents or cosmetic containing soapnut surfactant and whey or a product obtained during the Milchverarbei ^¬ tung permeate. It is disclosed in paragraph [0018] that acid whey (milk treated with lactic acid bacteria) can be used in the detergent, although sweet whey (for which it is not disclosed that it contains lactic acid bacteria) is preferred. Also permeate (from 99.5% of the bacteria are gefil ^¬ tert. See paragraph [0019)]) can encrypt according to the document be used. Finally, a heating of the detergent to 60 ° C is considered to be advantageous (see paragraph [0038]) or the embodiments), which is of course very harmful for lactic acid bacteria (if they are ever present in the detergent ^¬ present). In summary, the document neither discloses the minimum concentration of lactic acid bacteria in the detergent according to the invention nor does it recognize the essence of the present invention - the beneficial effect achieved by the combination of saponins and viable lactic acid bacteria in the detergent.

The English summary (World Patent Index / Thomson) of CN 102 719 491 A relates to a saponin extract of soap nuts ( "soap berry"), which will only be enzymatically treated with lactic acid bacteria and. This saponin extract can be used for Her ^¬ position of detergents however. in summary, the document discloses neither the inventive min ^¬ least concentration of lactic acid bacteria nor the pH of the detergent nor will ever realized that viable lactic acid bacteria in the cleaning agent must himself be present.

The English summaries (World Patent Index / Thomson) of the documents CN 104 087 645 A, KR 2012 0116053 A, CN 103 664 348 A and KR 2009 0083505 A relate to the fermentation ^¬ tion of ginseng with lactic acid bacteria for various purposes (but not for the preparation of a cleaning agent). The features of the present invention are neither disclosed nor suggested in these documents.

Saponins are glycosides of steroids, steroid alkaloids or triterpenes. They are natural surfactants with mostly bitter taste Ge ^¬. Saponins are widespread in higher plants and serve these as a defensive substances against fungus and insects ^¬ ate. Many saponins have - in addition to the surfactant - many beneficial effects, including against harmful germs. The fruits of horse-chestnut (Aesculus sp., In particular hippo- castanum), the rhizome of the soap herb (Saponaria sp., In particular ^¬ sondere officinalis), the bark of the soap bark tree (Quillaja), the fruits ( "Soapnut") of the washing tree (Sapindus sp , especially saponaria), the leaves of the birch (Betula) and also constituents of the ivy (Hedera sp., in particular Helix) have a high saponin concentration. Saponins from the aforementioned plant constituents or plants (and related plants thereof) are particularly suitable for the present invention. Highly preferred as saponins according to the present invention are Aescine (saponins from Rosskasta ^¬ never), saponins of the birch and Hederasaponine (saponins from the ivy). The structure of Aescinen example closer ^¬ be enrolled in Sirtori, Cesare R. "aescin: pharmacology, Pharmacopeia kinetics and therapeutic profile." Pharmacological Research 44.3 (2001): 183-193. The structure of Hederasaponinen described example ^¬ as closer in Elias, R., et al. "Triterpenoid saponins from the leaves of Hedera helix." Journal of Natural Products 54.1 (1991): 98-103.

In a preferred embodiment of the present invention, the detergent saponins from one of the front ^¬ reciprocating paragraph plants listed or any mixtures thereof, particularly saponins from saponin-containing components of chestnut, soapwort, ivy, birch or soap bark tree, or mixtures thereof. These saponins preferably account for at least 25%, preferably at least 50%, more preferably at least 75%, even more preferably at least 90%, in particular at least 95% or even at least 99% of the mass of all saponins contained in the cleaning agent.

Preferably, when the cleaning means is provided according to the invention as a liquid thinners ^¬ voltage, the Massenkon ^¬ concentration of all the saponins in the cleaning agent is at least 0.01%, preferably at least 0.025%, more preferably at least 0.05%, even more preferably at least 0.1% , In some preferred embodiments embodiments of the use or method of use according to the invention, it is also possible, the concentrate of the cleaning agent or the cleaning agent as a liquid dilution, for example, 1: 2, 1: 5, 1:10, 1:50, 1: 100, 1: 250, 1: 500 or 1: 1000 to dilute.

Lactic acid bacteria are bacteria that produce lactic acid. Although the lactic acid bacteria in the sense of the present invention may consist of a pure culture, they usually consist of a multiplicity of different types. Preferably, these are selected from representatives of Gat ^¬ obligations Lactococcus and Leuconostoc and representatives of the family of Lactobacillicae such as the genus Lactobacillus. In particular, be ^¬ vorzugt these are selected from members of the genus Lacto ^¬ bacillus such as Lactobacillus alimentarius, Lactoba ^¬ the Bacillus farciminis, Lactobacillus plantarum, Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus delbrueckii, Lactoba ^¬ the Bacillus brevis, Lactobacillus var. Lindneri, Lactobacillus book neri , Lactobacillus fermentum and Lactobacillus fructivorans.

The cleaning agent according to the invention has a pH of less than 5, preferably less than 4, more preferably less than 3.5 or even less than 3, in particular less than 2.75 or even less than 2.5. Thus, the durability of the cleaning agent is increased and, on the other, the effect (especially in relation to the Rei ^¬ nigungswirkung). Since the cleaning agent contains viable Milchsäu ^¬ acid bacteria, such acidic pH value can be achieved in that the cleaning agent is suitable for fermentation ge ^¬ was obtained (by provision of nutrients, etc.) or by fermentation. This means that the lactic acid bacteria (and other possibly present micro-organisms) acidify the detergent by metabolizing nutrients. Alternatively, or in addition, the detergent may be acidified by adding acid such as citric acid.

Therefore, the invention in detergent before ^¬ ferred embodiment comprises an acid, preferably selected from ethyl ^¬ acid, lactic acid, malic acid, citric acid and mixtures there of ^¬. Preference is given to a mass concentration between 0.2% and 6% acid, in particular between 2% and 5% acid, in the cleaning ^agent .

In a further aspect of the present invention, this preparation, preferably ground, as a soil or plant auxiliary used.

In a further aspect of the present invention there is provided the use of the detergent of the invention, or a dilution thereof (e.g., when the detergent is present as a concentrate), or the preparation of the invention.

In particular, the detergent of the present OF INVENTION ^¬ dung is suitable for cleaning hard surfaces in domestic, industrial or commercial, therefore, a preferred embodiment of the use according to the invention comprises the application of cleaning agent onto a hard surface, for treatmen ^¬ lung, in particular cleaning, the surface , Such surfaces consist for example of glass, ceramic, metal or plastic.

Likewise, the invention relates to a method for cleaning surfaces, comprising applying the cleaning agent according to the invention or a dilution thereof on the surface. Here, the applied agent absorbs dirt, which is removed here with ^¬ and colonized at the same time the surface with the (benign) lactic acid bacteria.

Surprisingly, it has been found that the dung OF INVENTION ^¬ proper detergent can be used as a treatment agent also a plant to promote growth or resistance of the plant. Both the lactic acid bacteria and the saponins (or the sugar yeasts, if present, and the saponins) contribute synergistically to this promotion. Therefore, a further preferred embodiment of the vorlie ^¬ constricting invention relates to the use of the cleaning agent of the invention (as treatment agents) to a plant or in the sub ^¬ strat (for example, soil or potting soil) of a plant, to the conveying ^¬ tion of growth or resistance of the plant; or a method which comprises the application of the cleaning agent of the invention (as treatment agents) to a plant or in the substrate (for example soil or potting soil) comprises a plant, the promotion of growth or resistance of the Pflan ^¬ ze. In particular, the cleaning agent according to the invention acts ^against infestation with pathogens such as bacteria or fungi. This treatment of plants may be performed independently of the use (or method) of the invention for cleaning surfaces or in combination therewith. For example, by emptying the (remaining or soiled) detergent (or a dilution thereof) into the substrate after the cleaning application.

Although WO 88/00579 Al discloses a means for improving and maintaining the natural health of soils and plant growth on the basis of a good containing lactic acid bacteria from the acidification of bread in water. However, the addition of saponins, which supply means amplifies the benefits of pure invention, surprisingly, does not he imagines ^¬ in that document or suggested is.

Surprisingly, it has also been found that the cleaning ^¬ restriction means of the invention is suitable, odors in effluent (for example, a wash basin) and channel (in particular in household or Ge ^¬ rack) to eliminate or prevent odors. Therefore, a further preferred embodiment of the present invention, the use of the cleaning agent according to the invention in drain or channel or a method which comprises the application of the cleaning agent according to the invention in drain or channel. This can be independent of the use according to the invention

(or the method) for cleaning surfaces or in combination with this. For example, after cleaning the (remaining) detergent

(or a dilution of it) is emptied into the drain. Preferably, it is allowed to act there for a longer time, for example at least 3 minutes, preferably at least 10 minutes, in particular ^¬ at least 60 minutes. The colonization of the runoff with the lactic acid bacteria according to the invention leads to the avoidance of unpleasant odors. Preferably, the treatment is overnight, so that the colonization can take place as undisturbed.

Furthermore, it has surprisingly been found that the cleaning agent according to the invention for the grooming of animals (eg domestic animals and farm animals, such as horses, dogs and cats) is well suited. Therefore, a further preferred exporting ^¬ approximate shape of the present invention, the use of the inventive cleaner, or a dilution thereof in the skin care or skin cleaning, and a method comprising the grooming or fur cleaning with the cleaning agent according to the invention, or a dilution thereof. It has surprisingly been found that animals (for example horses) also profit from it when they absorb the cleaning agent according to the invention (as a dietary supplement) or a Ver ^¬ thinning thereof via the diet. Therefore, another preferred embodiment of the present invention is the use of the detergent of the invention or a dilution thereof as a dietary supplement for animals or a method comprising administering the detergent of the invention or a dilution thereof as a dietary supplement for animals.

In another aspect of the present invention, a production method for the inventive cleaner is disclosed, comprising providing a lactic acid bacteria preparation comprising and the addition of a saponin and, where appropriate, ^¬ water to the drug. The active mixing of the ingredients ^¬, for example by stirring or shaking, is advantageous in order to achieve a homogeneous mixture. The person skilled in the art can calculate advantageous addition amounts from the preferred concentrations of the abovementioned constituents mentioned above. Gege ^¬ appropriate, with acid can be by addition or by formation during fermentation (preferably the acids mentioned herein), the pH adjusted to a pH value below 5, preferably below 4, more preferably be reduced below 3.5, in particular below 3.

In a further preferred embodiment of the manufacturing method, the method comprises at least one Filtrati ^¬ onsschritt, especially after the fermentation. Preferably, the detergent is filtered so that no more than X% of the solid particles contained in the cleaning agent having a mean diameter by having at least 50ym an average diameter of more than Y mm, where X = 20, preferably X = 10, more before ^¬ Trains t X = 5 even more preferably X = 1, in particular X = 0.1 and Y = 2, preferably Y = 1, more preferably Y = 0.5, even more preferably Y = 0.1, in particular Y = 0.05. In another preferred execution ^¬ form of the manufacturing method, the method comprises at least one filtration step through a filter having a pore size of at least 5ym and at most 1.5 mm, preferably at most 1 mm, more preferably at most 500ym, even more preferably at most lOOym, especially at most 50ym.

The filtration step takes place, for example, with filter plate for wine and spirits with a pore size of approx. 5-10ym or with filter plates for fruit juices with a pore size of approx. 10-30ym.

In a particularly preferred embodiment of the production process, the preparation comprising lactic acid bacteria is a fermentation sludge, preferably obtained from the spontaneous acidification of sourdough bread. Gärschlämme comprising lactic acid bacteria are familiar to the skilled person and already well documented in public outside the range of ahead ^¬ invention. Gärschlämme usually contain no pure culture - the combination of many different lactic acid bacterial strains result in very beneficial effects, especially in relation to the control of undesirable microorganisms. For example, suitable Gärschlämme be prepared by methods which are taught in DE 38 02 840 AI or in DE 199 32 055 AI.

In a further preferred embodiment germinated cereals, preferably selected from barley (eg malting barley) and wheat (eg brewing wheat), are added to the preparation comprising lactic acid bacteria, preferably before the fermentation. For example, the grain can be soaked for 3-5 days in water at a temperature of 15 ° C-18 ° C and then brought to Kei ^¬ tion before addition. Alternatively or additionally, preferably by fermentation, one or more of the following parts of plants for lactic acid bacteria comprehensive preparation are added: citrus (preferably the whole) and herbs or fruits such as nettle, dandelion, oregano, Basili ^¬ Kum, rose hip, sea buckthorn. In both cases it has been shown that the cleaning performance improves, especially with regard to the long-term effect (prevention of, for example, weather-related re-contamination of cleaned surfaces). In particular, longer lasting gloss of the surfaces after cleaning was evident.

As already mentioned, a low pH of the invention ^shown SEN cleaning agent is preferred in order to increase shelf life. Therefore, a further embodiment of the production process of the present invention comprises the fermentation with lactic acid bacteria before or after the addition of the saponin, preferably for at least two days, more preferably for at least one week. more preferably for at least two weeks, more preferably for at least three weeks. Preferably, the Fer ^¬ mentation is performed until a pH value of below 5, preferably below 4, more preferably less than 3.5, more preferably of less than achieved. 3

Particularly preferred is the addition of saponins before ^¬ be said fermentation. As a result, the advantageous effects of the cleaning agent are increased, in particular by a positive effect on the fermenting lactic acid bacteria or the optionally present sugar yeasts.

Another advantageous effect of adding the saponins prior to said fermentation is especially when the saponins are added in the form of saponin-containing plant components as described herein. Since saponins usually occur in plant constituents, the fermentation in the presence of the plant components causes a better dissolution of the saponins and promotes the shelf life. In addition, such a prior, energy-consuming and costly extraction of saponins omitted.

In a most preferred embodiment of the method according to the invention, the saponins are added by saponin-containing plant constituents, in particular chestnut (preferably the fruits, in particular the genuine horse chestnut), ivy (preferably the leaves, in particular the common ivy), soapnut tree (preferred the fruits -. "soap nuts"), birch (be ^¬ vorzugt the leaves) or soapwort (preferably the rhizome, in particular the genuine soap herb), are added to the lactic acid bacteria comprehensive preparation As mentioned, these are known for their high saponin content and therefore excellent for the present invention is suitable. Preferably, the plant parts are comminuted prior to adding, in particular by grinding in a mortar, optionally with the addition of essential oils such as the. Preferred above ma ^¬ chen in the thus prepared cleaning agent saponins from chestnut and / or ivy at least 50 %, Preferably at least 75%, more be ^¬ vorzugt at least 90%, especially 99% of the mass of the beinhal ^¬ ended saponins.

With "mass concentration" in liquids the mass is [kg] of the solute per volume of solution [1]. It is usually expressed as a percentage and then refers to the mass of solute (in grams) per 100 ml of solution.

The term a "viable" microorganism is to be understood that the microorganism (25 ° C eg for sufficient moisture and nutrients ^¬ materials) is carried out at suitable to life conditions metabolism and optionally ver ^¬ multipart. Such a microorganism is also considered viable to consider if he is performing no metabolism (possibly frozen or dried state), unless metabolism adjusts again when alive reign geeig ^¬ designated environmental conditions. these environmental conditions are known for lactic acid bacteria and Zuckerhefe, in particular they multiply under optimal conditions as a Temperature of 30 ° C and sufficient nutrients and moisture.

By the term "cellulolytic" with respect to a bacterium is meant that the bacterium can use cellulose as a nutrient, in particular "cellulolytic" means that the bacterium is in a cellulose-based nutrient medium (eg 1 g (NH ₄ ) ₂ S0 ₄ , 1 g K ₂ HP0 ₄ , 0.5 g MgS0 ₄ , 0, 001 g NaCl, 15 g agar, 10 g carboxymethyl cellulose (CMC) and 0.2 g cycloheximide per liter of distilled water) in culture.

The present invention will be explained in more detail with reference to the following ^examples , to which it is of course not limited.

Examples

Example 1 - Preparation of the cleaning agent as a concentrate

Grind or grind 100g of dried horse-chestnuts (from Aesculus hippocastanum) and mix with 10ml of an essential oil. Add 890ml of Original Kanne Brottrunk® (containing a fermentation sludge of lactic acid bacteria).

Ferment for 4 weeks at a temperature of 36 ° C and then remove the solids with a fine sieve. Since ^¬ according followed by a maturing and settling of further 2-4 weeks at about 20 ° C. The subsequent filtration (pore size 30ym) and filling into a canister completes the production of the cleaning from.

Example 2 - Preparation of the cleaning agent as a concentrate

Grind or grind 50g of dried horse-chestnuts (from Aesculus hippocastanum) and 50g of ivy (Hedera helix) and mix with 10ml of an essential oil. These 30g wholemeal spelled flour, 860ml lukewarm water, 5g Organic leaven dried (milk ^¬ acid bacteria included) and give 5g organic yeast.

Ferment for 4 weeks at a temperature of 36 ° C and then remove the solids with a fine sieve. Since ^¬ according followed by a maturing and settling of further 2-4 weeks at about 20 ° C. The subsequent filtration (pore size 30ym) and filling into a canister completes the production of the cleaning agent.

Example 3 - Application

Dilute 20 ml of the concentrate obtained in the preparation with warm water to 1000 ml and apply with a mop on a stone terrace surface so much of the dilution that the entire terrace surface is wetted with the dilution. Leave for three minutes, then rinse off the terrace with water. With the excess dilution, water plants in the garden and / or spray the leaves.

The terrace area could be cleaned effectively, whereby a lasting colonization by other organisms (mushrooms, lichens) was avoided. The treated plants showed stronger growth and less fungal infestation compared to untreated plants. Particularly good results were obtained with the above-mentioned dilution compared to a conventional cleaning agent used on wooden floors. Here next to the gentle cleansing and nourishing effects were observed that showed up in fresh color and luster, especially after mehrma ^¬ jump-cleaning.

Example 4 - Application

The use of the present invention as a plant strengthening Medium showed pronounced effects on growth, leaf gloss and leaf color. Furthermore, a "lotus flower effect" has been observed in plants after repeated Besprü ^¬ hen over two weeks.

Example 5 - Comparison test

The following products or formulations were compared in a test:

A) Commercial all-purpose cleaner with artificial surfactants and vinegar additive

B) Probiotic cleaner with "Effective Microorganisms" and artificial surfactants

C) The ingredients (bread drink, Rosskas ^¬ tanie mixture, ivy and soapwort, fragrance oils) are mixed and used after a short time - an embodiment of the cleaning agent according to the invention

D) The constituents (bread drink, mixture of horse chestnut, ivy and soapwort, fragrance oils) are mixed and fermented ^¬ as described in Example 1 - another Ausfüh ^¬ tion form of the cleaning agent according to the invention

E) The components (Brottrunk, mixture of horse chestnut, ivy and soapwort, "leaf mold", fragrance oils) can be mixed ge ^¬ and fermented as described in Example 1 - ei ^¬ ne another embodiment of the inventive cleaner.

F) The ingredients (germinated grain, organic sourdough, organic yeast, mixture of horse chestnut, ivy and soapwort, wild ^¬ herbs and wild fruits, lemons, foliage compost, fragrance oils) ^¬ mixed, fermented and processed as described in Example 6 below - Another embodiment of the cleaning agent according to the invention.

The comparison was made in the following points:

Product stability / durability

Cleaning hard and soft surfaces

Car cleaning (exterior, interior, glass, rims) Surface care (color fresh, gloss)

drying time

Again, pollution

Effect on plants (growth, leaf gloss and color)

Animal husbandry in agriculture (stable odor,

Slurry)

Animal care (grooming, fly pollution)

The result among the tested products or formulations shows that the formulations "E" and "F" are generally on effect ^¬ most, where "F" leads to better results than "E", especially in animal husbandry (stable smell, etc.) and animal care (grooming, fly pollution). A long-term test lasting one year has confirmed the above results.

Example 6 - Preparation of the cleaning agent

Purified grain (malting barley or brewing wheat) is soaked in water and germinated at a temperature of 15-18 degrees Celsius. Enlarged enzymes are thus formed in the meal body.

The fermentation takes place using the following components:

50g dried and ground horse chestnuts

50g dried and ground ivy, soapwort, birch leaves or foliage compost

40g of freshly germinated cereal

5g organic sourdough (includes lactic acid bacteria)

5g organic yeast

850ml untreated water (about 30 ° C)

At a temperature of 36 ° C to ferment for 4 weeks and remove the check circuit solids with a fine screen (but kei ^¬ nesfalls sterilize by filtration). The pH of the cleaning agent is already between 2.5 and 3.0 after the fermentation. To the filtrate (volume: 840 ml) are added the following ingredients:

25g pureed, (etc nettle, dandelion, oregano, basil, rose hips, sand ^¬ thorn, lemons) antioxidant highly effective fruits and Kräu ^¬ ter

25 g pureed lemons

10ml lemon oil or another essential oil

At a temperature of 36 °, the second fermentation is carried out for 2 weeks, after which the solids are removed with a fine sieve (but in no case sterile filtered). The pH has dropped further due to the added lemons and the postfermentation.

It follows at 20 ° C a maturation and settling phase for 2-4 weeks. If desired, the pH can be adjusted to the target 2.5 by adding an acid (e.g., citric acid)

Finally, it is again filtered (pore size of the filter: 30ym) and the filtrate bottled in a canister.
